PLEASE HELP!!

im 18!! so for the past few days my back has been very sore and when i wipe my vagina it hurts a lot, slight burning when peeing which went away?? i am going to go to the doctor ASAP but its closed for the day, does anyone think this looks similarly to herpes😭 also the day before this started me and my boyfriend had sex like 3 times and he ate me out for the first time
